press <Alt><F2> and start typing the name of the application you're looking for (it'll appear after a few characters)
open a Konsole, and try e.g. to type 3 characters, and then press <tab> (then you'll see all possibilities with that starting characters)
open the menu (I think you've done that already), and search in every menu
(I'd take a look in menu>>morePrograms>>configuration)
